The passive E 110 Sub subwoofer module is equipped a high-performance 10-Inch woofer, developing a tight, low-range bass. This passive subwoofer is the perfect add-on for applications demanding even more powerful low-end response. Power is provided by either an EA 600 Power amp module, or by the companion E 110 Sub A actively powered sub; connections are made using the NL4/Speak on Input on the rear panel. The E110 Sub can be positioned vertically or horizontally. Used vertically, the integrated E-Connect coupler on the top panel also serves as a pole mount for further EP 1, EA 600, and E 435 modules.
